Deuterium isotope effect on the dissociation of weak acids in water and deuterium oxide

The Effect of Deuterium Depleted/Enriched Water on the Growth of A549 and HepG2 Cell Lines

Background: Although advances in cancer therapy continue to develop, the overall survival rate is poor for some cancer cases. The search for a new adjuvant strategy is the focus of cancer treatment. There is some evidence suggesting a change in the mechanism of cell function by a change in the content of deuterium in the medium. So, the aim of this study was to investigate the ...

Deuterium Isotope Effects on the Silver

Solvent deuterium isotope effects support the view that the p-N02 and p-Me derivatives of benzaldehyde S.S-diethylacetal undergo silver ion-promoted hydrolysis in water by different mechanisms. scheme common [3] for O.O-acetals in the presence of H30 + ions, while for the latter we suggested a bimolecular A2-type mechanism with one (or more) water molecules in the slow phase of step (3). The co...

Carboxypeptidasey from Saccharomyces cerevisiae Conformational Difference Reflected in Kinetic Behaviour in Water and Deuterium Oxide

Inverse Deuterium Isotope Effect in the Intersystem Crossing of Diphenylcarbene

They are important chemical intermediates whose spin state dependent chemistry is implicated in a large number of organic reactions [l-4]. An important feature relevant to an understanding of many of their physical and chemical properties is the small energy gap separating the lowest singlet and triplet states. In fact for a number of carbenes these two states are in equilibrium at room tempera...

Heavy Atom- and Deuterium Isotope Effect in Bis-(Phenylethinyl)-Mercury

The influence of mercury as a heavy atom on the spin orbit coupling is investigated in bis(phenylethinyl)-mercury and its deuterated derivative. From the experimental results we draw the following conclusions: a) the symmetry of the molecule is D2 , b) the large spin orbit coupling of the mercury atom is introduced via djr p^-interaction, c) local a jr-transitions and vibronic coupling are of n...
